The 20-year-old moves to Selhurst Park for an undisclosed fee after spending the summer captaining Spain at the Under-20s World Cup.

The Seville-born player becomes Ian Holloway's fourth signing of the summer, joining Dwight Gayle, Jerome Thomas and Steven Dobbie in south London.

Campana told the club's official website: “I’m delighted to become a Crystal Palace player. Over the last two years, I’ve had some problems with my hometown club, but I’m really excited to play in the Premier League.

“I think it’s a good step for me and I’m really excited and looking forward to meet all the boys and start as quickly as possible.

“I got the first interest through my agent, who said that Crystal Palace were interested and straight away I said ‘yes’ because for me it was a dream to play in England, especially in the Premier League. I hope to help the team stay in the league and then move forward.

“What I like to think are my best qualities are to keep the ball and to have good distribution. I have always been a typical Spanish midfielder and I like to move forward and score goals.

“I scored a lot of goals when I was in the academy at Sevilla. That’s what I want, but especially to keep the ball and to organise the team.”

Campana has progressed steadily through the national team ranks, featuring at every level up to U20s, but played just 20 times for Sevilla in his two seasons with the senior team; a fractured foot restricted him to just five league games in 2012-13.

And Palace boss Ian Holloway lauded the acquisition, earmarking Campana as a star of the future.

"I’m absolutely delighted," Holloway added. "Everybody knows the way I want to try and play football and how fantastic Spain have been over the past few years, so I’m delighted to get a lad of this quality.

“I think he’s a fantastic player, his maturity is unbelievable, and the way he plays the game is the way I believe it should be played. He’s going to be a great star of the future and the present.

“We’re going to try and do as well as we can in this division and making signings like this is really going to help us.”
